Answer:
Adaption
Explanation:
In the case when the practice of cells turn on some enzymes production and turn off the others so that the response to the environment i.e. changed is known as an adaption.
In this, the organisms are adjusted according to the environment
So as per the given statement, the adaption is the answer and the same is to be considered
Because hormones secreted by endocrine glands regulate the activity of body cells ..the release of body hormones into the blood is controlled by a stimulus either causes an increase or a decrease in the amount of hormone secreted .
An example of a population in which evolution could take place in a relatively short period of time could be pathogenic bacteria exposed to antibiotics.
Answer: Option A
<u>Explanation:</u>
Evolution if takes place within a short period of time say the next generation that is called as micro evolution. This is caused when a specific organism exposed in a different environment at once modifies its genes to suit the new environment. This phenomenon can be very well seen in the pathogenic bacteria which are exposed to antibiotics.
When an antibiotic is prescribed to bacteria initially it nullifies its effect by destroying it. When continuously exposed to a certain antibiotic some bacteria dies but there are few which becomes resistant to it and survives. This on the other hand multiplies producing a generation that can’t be touched by the antibiotic.
Answer: The correct option is C (Dendrites, Cell body, Axon, Axon terminals)
Explanation:
The transfer of information from neuron to neuron takes place through the release of chemical substances into the space between the axon and the dendrites. These chemicals are called neurotransmitters, and the process is called NEUROTRANSMISSION.
The order of neurotransmitter/receptor interaction that results in an electrical signal impulse and the release of another neurotransmitter for interaction in the synaptic cleft (signal conduction through a neuron) is from Dendrites--> Cell body--> Axon-->Axon terminals>
DENDRITES extends from the cell body of a neurone to receive messages at neuromuscular junction from other neurons. The CELL BODY directs all activities to the axon. The AXON is a long single fibre that transmits messages from the cell body and ends in terminals forming a synapse. Nerve impulses arrives at the axon terminal causing the release of neurotransmitters. The neurotransmitters binds to receptors at the dendrites of another neurons. The electrical signal impulses generated causes the release of neurotransmitters in another neuron.
